Payments are made to you 30 days after a months accrual. Meaning if you accrued $100 in January, you will be paid March 1st or thereabouts.
When the revenue you have generated for your account exceeds $25 your payment is posted in sent to your address every month. If you do not reach the $25 minimum within a month, the amount generated is carried forward to the next month. You can view your revenue and sales statistics live on your Commission Junction Account throughout the month to see how you are doing.
